<p>
	This method actually opens a connection to the database.
      </p>
<p>
	Any data specific to the connection (such as 
	a database handle created by the database API when opening the connection) must be stored in a private structure
	(which should be defined in the <code class="filename">gda-&lt;providername&gt;.h</code> file as a 
	<code class="classname">&lt;Providername&gt;ConnectionData</code>); this private structure's adress should be
	"attached" to the <a class="link" href="GdaConnection.html" title="GdaConnection">GdaConnection</a> object using the
	<a class="link" href="libgda-5.0-Misc-API.html#gda-connection-internal-set-provider-data" title="gda_connection_internal_set_provider_data ()">gda_connection_internal_set_provider_data()</a>.

<p>
	This method actually closes a connection previously opened by the 
	<a class="link" href="ch44s04.html#prov-open-connection" title="open_connection() - mandatory">open_connection()</a> virtual method. This method is not mandatory for
	virtual providers.
      </p>
<p>
	The connection specific data for the database API can be retrieved using the
	<a class="link" href="libgda-5.0-Misc-API.html#gda-connection-internal-get-provider-data" title="gda_connection_internal_get_provider_data ()">gda_connection_internal_get_provider_data()</a> method.
